No functional edge for robotic knee replacement, and a score for lytic lesions
A randomised-trials-only meta-analysis finds robotic total knee replacement no better functionally than conventional and slower to perform; how common osteoporosis is in men on androgen deprivation; letting a metacarpal fracture move early; and external validation of the Bone-RADS score for lytic bone lesions.
The edition in brief
Today's orthopaedics edition opens on a question many units are spending heavily to answer. A meta-analysis restricted to 24 randomised trials (3,425 patients) found robotic-assisted total knee arthroplasty gave no significant advantage over conventional surgery in WOMAC function, Knee Society or Oxford Knee scores, pain, range of motion or hospital stay, while operative time was about 22 minutes longer; evidence certainty was low to very low, and the authors say current data do not support routine robotic adoption. A meta-analysis of 91,913 men with prostate cancer found osteoporosis in 22% and low bone mass in 42%, underlining bone health in a group often on androgen-deprivation therapy, though it measured only prevalence. A small randomised trial found an intramedullary K-wire with immediate mobilisation restored hand function faster than transverse K-wire fixation plus splinting, with the same final outcome. A clinic pearl restates open-fracture first aid. The practice-changer is an external validation of Bone-RADS, the American College of Radiology score for lytic bone lesions: sensitivity 97% and negative predictive value 92%, supporting it as a triage aid for deciding which lucent lesion needs referral.
Robotic knee replacement: no functional advantage, longer operations
On current randomised evidence, robotic knee replacement offers no functional or pain advantage over conventional surgery and takes longer, so routine adoption is not justified by outcomes.
Bone loss is common in men with prostate cancer
Treat men with prostate cancer, especially those on androgen-deprivation therapy, as a bone-health population needing density assessment and fracture-risk management.
Let the metacarpal move: earlier hand function with intramedullary fixation
After stable intramedullary K-wire fixation of a transverse metacarpal fracture, early mobilisation restores hand function faster without harming healing.
Open fracture: the first hour still matters
In an open fracture, give antibiotics within the hour, check tetanus, cover the wound once and splint, documenting neurovascular status throughout.
A validated score to triage the lytic bone lesion
Use Bone-RADS to triage an incidental lytic bone lesion: its high sensitivity makes a low score reassuring and a higher score a prompt for referral.
